Need to skim coat an 8' ceiling (20'x30') & I do not want to buy a work platform ? How do I build 1?

I know it might be a little bit of an open end question. To narrow this down I would mention that I am planning to use some 2×4s that I have laying around and some plywood to build two of the below work platforms. I might add some pads not to scratch the existing hardwood floor but that is the next project for the same room

Is there a better way to build this ? I need the platforms to be long

Tool rental is the answer here. They will have everything from Drywall stilts to full on scaffolding. Making a strong frame isn't hard to do, but seriously if you are having to ask how to go about it, for safety reasons you might want to consider rental.

If you insist on making a platform, the end verticals should be full height, and for 2×4 construction, dispense with "joinery" as such, like yours is showing those small blocks between your horizontals is an accident waiting to collapse. Instead just overlap the 2×4's fully, and screw through them. Triple your crossing members, and soon you will have a sturdy platform.

Like below, add plenty of crossing supports, top, bottom, and a few at 45 degrees. Sheath the top with plywood. Using screws will let you disassemble after it's done.

Thanks a lot yes that makes sense for stability and sturdiness
Rental is not going to help for the below reasons

I do not want to buy one of these (the price is good -around 220CAD but it will force me to move very often

I also considered renting a scaffolding tower (33CAD/day) but it is also short and too tall for my needs https://www.homedepot.ca/en/home/tool-and-vehicle-rental/p.scaffold-tower-5.11072.html

This is why I decided to build my own.

Safety rules for these platforms say "lock the wheels" so …
that is probably the SECOND RULE so you need to decide if we play by rules here or not and reevaluate this
The pros stay on the platform and push themselves along..
Will check with HomeDepot and maybe Lowes today to see what they have but I expect this job to take me a while (I will be doing it over the weekends or in the afternoon) so renting the above or buying something bigger might not work

From your dimensions, it appears that the sides, top, front and back could be made from a single piece of 3/4" plywood set on a simple frame. In essence you are making a box of plywood without the bottom. Cut the plywood sides a bit short so they don't hit the ground. The front and back ends must be plywood too, to prevent racking.

Only 4 feet with pads touch the ground. The 2×4 stretcher is needed to give something on which to screw the plywood. Will be strong, stable, easy to move if you put handles on the ends. Here is the frame. Just wrap it with plywood and get to work.

PS, you could make the stretchers out of 2×2 to save some weight. It's only purpose is for screwing the plywood together more easily. Theoretically, the entire project could be made without any frame (plywood boxes are very strong), but I'd feel safer if there was decent purchase for the screws.

yes that could be an option to build the sides from construction plywood and not to overbuild the frame

my only problem with these is that I will need a few of them in order not to have to move the all the time
then I need to set them in such a way that I can jump (to say so) from one to the other without risking an accident
the next thing is that I will not be able to return them and selling like 4 of them is going to be a challenge

I ve used these. Only 11 lbs, moving around isn t an issue.

Scrap off the spilt mud, clean, and return them after use. You'll be 20" off ground. How old are you, you worried about busting a hip?

not that old yet
more worried for an unexpected lateral move of the platform that is under me which would send my flying in the air ..

I have seen tapers standing on a 5 gal plastic bucket. They could roll it from edge to edge and move like that. Then I read in the paper how a taper in Tennessee was doing that, lost his balance and plunged headfirst to the concrete sidewalk 3 floors below. The sidewalk wad not damaged. Unfortunately, the taper died.

and nothing like that could happen with stilts right ?

If I built the stand you described, I think I'd put carpet strips across the runners to make it easier to slide as well as protect the hardwood floors. I'd probably position that bottom stretcher (across the narrow distance) to the top of the long runners, near each end. That keep them away from the floor but still providing the rigidity.
